The Dryden Aqua Air Diffuser is a semi-flexible, high-efficiency fine bubble air diffuser available in 9 different lengths, depending on the air through-put required . It provides oxygen transfer rates of up to 5kg/kw, 10m3/h of air and 1 kg of O2/h. Its semi-flexible construction with its own internal ballast will stay on the bottom of tank or pond without the need to be anchored to the floor. The Dryden Aqua Air Diffuser combines excellent performance with cost effectiveness for aeration, oxidation and biological treatment. Dryden Aqua Air Diffuser Key Features Semi-flexible, tubular construction Self weighted Available in 9 lengths from 0.3 – 3m. Air handling capacity from 1 – 10m3/hr Less than 0.2 Bar (3 psi) pressure differential Oxygen transfer efficiency up to 5 kg/kwhr Resistant to calcification Easy to clean and maintain Robust and long-lasting (typical lifespan is 5 – 10 yrs) Built in non-return valve Stainless steel and plastic construction Can be used with Air, N2, CO2 Oxygen Transfer Performance Surface aerators waste a huge amount of kinetic energy throwing the water into the air, transfer coefficient is 1 kg to 2 kg of oxygen per kW. Membrane diffusers are more efficient at 2 kg to 3 kg of oxygen per kW. The Dryden Aqua diffuser at over 5 kg is therefore the most efficient fine bubble diffuser available and is ideal for retrofit applications as a simple drop in product for tanks and ponds in Aquaculture and Waste Water Treatment.

Point Four Plastic Micro Bubble Diffusers (PMBD) are one of the most efficient diffusers available, allowing you to increase yield while controlling the cost of expensive gases. Made from premium materials and subject to rigorous testing, PMBDs provide the kind of performance and reliability our reputation is built on. Point Four diffusers use a specially developed, ultra fine pore ceramic plate that produces a cloud of extremely fine bubbles of approximately 100–500 microns; far superior to airstones, porous hose or membrane type designs. The flat plate design ensures uniform bubbles across the entire surface and minimizes bubble coalescence to achieve an absorption rate in excess of 80%, depending on depth and flowrate. Bubbling pressure is 25 to 35 psi (1.7 to 2.4 bar). • Robust construction—ceramic plates set in an injection moulded plastic base with solid brass connection fittings.• Flexible, modular design lets you easily add or subtract diffusers as your needs change. Applications for micro-bubble diffusers include pure gas applications (pure oxygen, carbon dioxide), high-density hauling, holding/grow out tanks and emergency aeration. Note: Diffusers are also known as airstones.

Following successful field trials of a new micro bubble diffuser designed for the fish farming industry, Mantec has now launched an enhanced variant of the product into the market place under the brand CORALith. Building on our heritage of supplying more than 300,000 ceramic diffusers in the past 20 years, this new micro bubble diffuser introduces very small bubbles into the body of water, resulting in more surface area per unit volume and greater oxygen transfer exchange. In addition, agglomeration of bubbles as they rise to the surface is minimised. Mantec has been active in the supply of ceramic diffusers into the aquaculture sector since the 1990s. In recent times, the sector is increasingly demanding diffusers which produce the finest bubbles to ensure adequate and efficient oxygenation of the water in which fish are farmed. The need for finer bubbles is grounded on maximising the oxygen transfer at greater water depths.With this in mind Sterner's new Mantec diffuser is based on a porous ceramic tube, having a closely controlled pore size of one micron. This results in even, fine bubbles to produce efficient oxygen transfer. Fitted with two square stainless steel end caps, the CORALith diffuser assembly can be positioned in the tank in any horizontal orientation, without the operator having to be concerned that the diffuser is sitting flat on the base of the tank. The diffuser assembly is designed with a replaceable ceramic tube.Furthermore, the diffuser has been designed to minimise any potential leak paths, thereby ensuring the efficiency of oxygen transfer. Thanks to its robust construction, the operator need not be concerned about removing the diffuser from the tank when the oxygen feed remains switched on. In addition, the hose tail coupling does not rely on push-fit connections, instead it is secured with a British Standard Pipe thread to provide a secure connection with the mating hose.

WEDGE-LOCK™ uses an ultra fine pore ceramic producing a high Absorption Efficiency (AE) allowing you to increase yield while controlling the cost of expensive gases The Point Four WEDGE-LOCK is a modular system of microbubble diffusers and end sets that fit together to form a bank of up to eight units. Oxygenation capacity can be increased (or decreased) as your needs demand by simply changing the number of diffusers used for greater flexibility and minimal downtime.Designed for total ease of use, WEDGE-LOCK™ modules ‘Twist and Lock’ together to form an air-tight seal without the use of tools. Hose with push-in fittings connects the diffuser banks to the gas supply, significantly reducing set-up time and effort.Manufactured from tough plastic, WEDGE-LOCK™ will not corrode and is resistant to the Sun’s ultraviolet rays. The diffuser’s streamlined wedge shape improves stability in tanks with high water flow and offers less resistance in self-cleaning tank systems.
